It is possible in the we architecture for a single resource to have 
multiple URIs. However, I don't think this is the case here. Unless 
these servers and file systems are essentially views of each other such 
that changing one simultaneously changes the other three, then these are 
different resources with different URLs that happen to emit the same 
representations. They are not normally the same resource.

Some of these might be the same resource if, for example, 
pixel.recoil.org is a DNS alias for staging-server.local or the server 
on pixel.recoil.org maps /My Desktop/staging/ to the root of the files 
its serving, but if these are not the same systems then these are not 
the same resources, even if the representations are bit-per-bit 
identical. The URI identifies the resource, not the representation.
